boats
are
equipped
with
a
highly
innovative fuel system. This system is designed
to provide you with years of trouble-free service.
Some of the latest innovations related to fuel handling
safety are also incorporated into the fuel delivery system.
The system uses a fuel pump mounted in a capsule
that is installed directly in the fuel tank. A similar system
has been used in automotive vehicles for many years
and has demonstrated reliable service. The pump sys-
tem in your boat was specifically designed for the ma
-
rine environment and contains a number of added safety
components that are unique to the marine environment.
Because of the special nature of the design, there are no
user-serviceable parts. Any parts in need of service or
maintenance will need to be addressed by an authorized
MasterCraft dealer. The technical team there is equipped
with the special tools necessary to disassemble and ser-
vice the fuel capsule and associated parts.
The fuel line that travels in the boat’s bilge area from
the tank to the engine is a special multi-layer armored
line that is covered with a special material known as a fire
sleeve. The fire sleeve affords protection to the fuel line
in the unlikely event of a boat fire.
The sleeve is colored orange in order to afford easy
identification of the fuel line. MasterCraft recommends
daily inspection of the bilge for foreign materials and the
possibility of gas or oil leakage detection. As part of your
daily inspection, include a visual check of the orange
fire–sleeved fuel line. If you see damage to the sleeve
or line or in any way suspect damage or fuel leakage,
DO NOT START YOUR BOAT!
Immediately call an au
-
thorized MasterCraft servicing dealer and let him or her
assess the situation.
Indmar Engines
The following information applies to boats equipped with
Indmar engines:
What Type of Gasoline To Use
All standard Indmar EFI engines run on unleaded fuel
of 89 octane or higher. Indmar recommends purchasing
fuel from a supplier that advertises that their fuel meets
“TOP TIER” specifications. This fuel has additives and
detergents that will reduce the build-up of deposits in
the engine.
The intention of the TOP TIER detergent gasoline
standards is to create a winning situation for gasoline
retailers, engine manufacturers and boat operators.
Currently, many gasoline retailers provide fuels with
lower-quality additive packages that can build up de-
posits on fuel injectors and intake valves. Others can
build up deposits in combustion chambers and may
lead to intake valves sticking. These lower levels of ad-
ditives can have a negative impact on engine perfor-
mance and vehicle responsiveness.
For a current list of gasoline retailers supplying TOP
TIER gasoline, go to
www.toptiergas.com and click on
RETAILERS.
When the Boat Is Not Used
for a While
Indmar recommends the regular use of Sta-Bil® fuel
stabilizer for boat users whose outings consume less
than a tank of fuel every two (2) weeks. Today’s fuels
are more susceptible to degradation, and the use of a
quality stabilizer will help ensure fewer problems for the
occasional boater.
If the boat has not been used for more than thirty (30)
days and fuel remains in the tank (even stabilized fuel),
the engine may run poorly until the “old” fuel is used
up. The manufacturer will not pay for repairs to compo-
nents that are inoperable or damaged from old and/or
poor quality fuel, as this is not covered under the en-
gine warranty.
